One other change that showed up when gathering data for this list was that
the Oracle Database 12c prerequisites package was renamed between beta &
GA to better match the database naming style - previously it was called
group/prerequisite/oracle/oracle-rdbms-server-12cR1-preinstall
but is now
group/prerequisite/oracle/oracle-rdbms-server-12-1-preinstall.
Fortunately, you don't have to type in the whole FMRI to install it,
pkg install oracle-rdbms-server-12-1-preinstall is enough.

Detailed list of changes

This table shows most of the changes to the bundled packages between
the 11.2 beta released in April, and the 11.2 GA release in July.

As before, some were excluded for clarity, or to reduce noise and
duplication. All of the bundled packages which didn’t change the version number
in their packaging info are not included, even if they had updates to fix bugs,
security holes, or add support for new hardware or new features of Solaris.
